Whereas ionizing krypton requires more energy than xenon (which decreases the mass utilization efficiency), this attribute also decreases the production of multiply charged ions. The lower mass of krypton with respect to xenon also decreases the sputtering yield approximately by the square root of the mass ratio.
physics - Why might krypton have a lower utilization fraction than ...
To adjust position on orbit, maintain intended altitude, and deorbit, Starlink satellites feature Hall thrusters powered by krypton. (emphasis added) Most of the electric propulsion systems that I've heard of use xenon.

I am trying to figure out if Xenon or Krypton produces more thrust for a given weight flow rate of fuel when the engine operates at the same discharge voltages. The information I find is mixed or I...
Does Krypton or Xenon produce more thrust in a Hall-effect thruster ...
Starlink satellites use krypton as propellant. This answer roughly estimates 2.3 kg of Krypton based on a total delta-V of 190 m/s and an exhaust velocity of 20,000 m/s. But how close is that to re...
